I have treated many cases of Hashimoto's thyroiditis
It has to be confirmed by FNAC (Fine needle aspiration cytology) of the thyroid.
Later in Thryoid function tests,the hormones will be low.
If you are suspecting ,Hasimoto's you have to go for FNAC.
But as far as your symptoms are concerned,i don't think it is hashimoto's.
Even normal individulas have raised Anti TPO antibodies
Apart from hashimoto's they are raised in Grave's disease,nodular goitre
So, a simple FNAC test will clear all the doubts.
If you come back with the FNAC report,i will clarify further
Wish you good health
